It isn't technically virtue signing since it's meant to be persuasive.

The post further down (well, up now) that's calling attention to the fact that the guy should replace his helmet because he used it (something that is common knowledge for most people young enough to only have worn single use helmets and is literally printed on the helmet and packaging) is a better example of virtue signaling since it states something basically everyone already accepts as fact and is only tangentially related to the article in the first place.

Unfortunately, the term virtue signaling has taken on a political meaning so you can't say it and expect the internet even if you mean it in the technical sense.
